more information. • sender –Specifies a particular sender to receive signals from. See Connecting to sig- nals sent by specific senders for more information. • weak –Django stores signal handlers as weak connect() method. • dispatch_uid –A unique identifier for a signal receiver in cases where duplicate sig- nals may be sent. See Preventing duplicate signals for more information. Let’s see how this works signals get sent many times, but you’ll only be interested in receiving a certain subset of those sig- nals. For example, consider the django.db.models.signals.pre_save signal sent before a model gets
